The apartment is great for a short term stay. Easy, fully furnished, modern. The location is ideal to discover Budapest, at the heart of the city.
However, the building - typical from downtown Budapest - makes it very dark, so there is only artificial light in there, no light from outside. And it can also get loud at night the weekends, because everything resonates so much inside the building.
Neighborhood
Good, central but also very touristy and busy - packed and can be loud.
